Rear tire loses pressure

[KSB]

The rear tire on my 2016 R1200RT-LC loses pressure very slowly; it goes from 44psi to ~35 psi overnight and then stays at that pressure. Developed a leak during my last trip and I had the leak plugged; can the plug re-seal itself when the pressure reduces to ~35 psi? The TPM tracks the pressure perfectly when riding and stops decreasing at ~ 35 psi. I use a valve stem cap at all times. The tire is a Michlean Road 5 with about 6K miles. A new tire is on-order, but I wanted to see if anyone has experienced a problem like this.

 

Thanks

Found another nail in the tire

Replaced the tire with new $$$

Cheaper than a blow out!

 

THANKS for all the feed back
